SPARK-ARRESTER.

SPECIFICATION forming part of Letters Patent No. 316,022, dated April 21, 1885.

Application filed November 13, 1884. (No model.)

To aZZ whom it may concern.-

Be it known that I, J AOOB ELA, a resident of Indianapolis, Indiana, have made certain new and useful Improvements in Spark-Arresters, a description of which is set forth in the following specification, reference being made to the accompanying drawings, in the several figures of which like letters indicate like parts.

My invention relates to appliances for arresting sparks in locomotive-stacks and re turning them, with the smoke, to the fire-box for consumption, and will be readily understood from the following description.

In the drawings, Figure 1 represents a side view of the stack and boiler of a locomotive, the stack being in vertical section so far as to show the construction and internal arrangement of the parts. Fig. 2 represents a front view of the deflector and its opening 0.

In detail, bis the barrel of the stack, extending up to the flaref. Attached to the top of this barrel by straps s, and at some distance above it, is a deflector, d, having an inclined top, 15, and an opening, 0, on the side fronting the cab, this deflector being placed within and surrounded by the flare f, as shown in Fig. 1. The openings between the deflector and thebarrel-mouth allow a ready draft, not only around the deflector, but also through the opening 0 and the top of the stack.

p is a pipe connected to the lower flare and running down along the outside of the barrel, as shown, and is intended for carrying the sparks, cinders, and smoke back to the firebox. This pipe opens into the flarejust be low the opening 0 in the deflector d, and runs back either outside the boiler on either or both sides, or may be carried back through a flue, if desired, inside the boiler, to connect with the fire-box, so that it will discharge its contents therein. The inclined top of the deflector d stops the cinders, sparks, exhauststeam, and gases, and turns them out through the opening 0, and they pass readily downat least the heavier portionsinto the opening of pipe 19, the steam supplying force to drive them back to the fire-box, where they I am aware that cones have long been used over the mouth of the barrel, and do not broadly claim the same as my invention; but I am not aware that a deflector provided with an opening like mine, in connection with a returning-pipe connecting with the fire-box,

has ever before been known or-used.

What I claim as my invention, and desire to secure by Letters Patent, is the following: 1. The barrel 1), provided with the deflector d, having the inclined top tand side opening, I

0, the deflector supported above the mouth of the barrel by straps s and within the flare f, all combined substantially as described.

2. The barrel b, provided with deflector d, having inclined top 25 and opening 0, the deflector supported above the mouth of the barrel by suitable straps, s, and Within the flare f, and one or more pipes connected to the lower portion of said flare for leading back to the fire-box, for returning the products of combustion thither, all combined substantially as described.

3. A sparkarrester for locomotives, wherein a deflectingtop having an inclined top and an opening in front is fixed above the mouth of the barrel, so that the opening in the deflector will be substantially over the opening of a return-pipe leading to the fire-box con- JACOB ELA.
